AN EXPERIMENTAL INVESTIGATION OF SURFACE CONDITIONS ON HYPERBOLOIDS AND PARABOLOIDS AT A MACH NUMBER OF 10

Abstract

Data on analytic bodies are presented for Reynolds numbers from 22 to 65,000 (based on model nose radius) at a Mach number of 10. The test bodies are hyperboloids having asymptotic half-angles of 10, 22.5, and 45 deg and paraboloids; data are presented for steady-state skin temperatures, surface pressures, drag, and total skin friction. Shock-layer pitot pressure distributions are presented for two hyperboloids at selected Reynolds numbers. The results include an assessment of the modified Newtonian impact theory for use in inviscid pressure distributions. The effects of ciscous interactions on skin temperature, pressure, drag, and skin fraction are examined. Comparisons with numerical results of second-order boundary-layer and fully viscous shock- layer theories are made.
